Location: Suryabinayak, Bhaktapur

Elevation: 1508 m.
Habit : Wild 

Is its a moss? if so then check with Huperzia sp. Specially Huperzia lucidula and Huperzia serrata although i have not checked its distribution record.

Looks close but I am not sure if it is listed in Nepal or not.
I am trying to find out.

Huperzia serrata (Thunb.) Trevis. is listed in Nepal but Huperzia lucidula is not listed as far as I know.
Compare with the image at:
This is a Pteridophyte, Huperzia sp.
The enclosed species is Huperzia javanica (Sw.) C.Yang. I was wondering what is the population status of this species in Suryavinayak forest nowadays? There were not many individuals when I went there 5 years ago.
So far I have noticed only one plant. I shall check in my next visit if there are any more.
Today I have noticed around 14 plants in same location.

Therefore, the northeast Asian plants should be treated as a separate species, H. asiatica (Ching) B.-Y. Sun & J. Lim. In addition, we believe that H. javanica (Sw.) C. Yang, regarded as conspecific or infraspecific with H. serrata (Thunb.) Trevis., is a distinct species based on the presence of a leaf petiole and serrated leaf margins, and the shape of the gemmiferous branchlets)
